Yeah - I liked this film too... I have also watched the original Russian version (first), but found it very hard to follow...

The films are essentially the same save the usual Hollywood razzmatazz...

There is a great energy about the actress, Natasha McElhone...

Read the book if you can by Stanislaw Lem... He's written hundreds of others - perhaps we'll see some of them come to the big screen one day...
